JOHN N. DERSCHUG, OF SYRACUSE, NEW YORK, ASSIGNOR TO SYRACUSE WASHINGMACHINE CORPORATION, OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK.

DRIVE MECHANISM FOR COMBINED WASHERS AND WRINGERS.

Original application filed January 31,

To all whom it may concern:

Be it known that 1, JOHN N. DERsoHUG, a citizen of the United States,and a resident of S racuse, in the county of Onondaga, in the tate ofNew York, have invented new and useful Im rovements in Drive Mechanismfor Comblned Washers and Wringers, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to mechanism for operating the movable parts of acombined washer and wringer as set forth in my pending application Sr.#355,515 filed January 31, 1920, of which the present application is adivision.

The main object is to provide a more dependable, safe and evendistribution of" power from the motor to the working parts of the washerand wringer without overloading the motor or overstraining any of thepower transmitting parts, and also to conserve the power and timerequired for various washing and drying operations in the same machine.r

Another object is to support-the wringer near one of the legs of thetripod in such manner that it may be swung to different positions overand away from the top of the vat without liability of overturning themachine and thereby to avoid the use of extra means of sup ort for thispurpose.

A further 0 ject is to assemble the various mechanisms upon the machinein such manner as to avoid excessive vibration thereof when inoperation.

Other objects and uses relating to other specific parts of the machinewill be brought out in the following description:

In the drawings:

Fig. 1 is a top plan of a clothes washing machine embodying the variousfeatures of my invention.

Fig. 2 is a transverse vertical sectional view of the same machine takenon line 22,

1920, Serial No. 355,515. Divided and this application filed October 25,1921. Serial No. 510,297.

from which power is transmitted to the dashers and to the wringer.

Fig. 5 is an enlarged sectional view taken on line 5-5, Fig. 3.

Figs. 6 and 7 are enlarged vertical sectional views taken respectively,on lines 6-6 and 77, Fig. 1.

Fig. 8 is an enlarged horizontal sectional view taken on line 88, Fig.2.

Fig. 9 is a horizontal sectional view taken in the plane of line 99,Fig. 7.

The machine, as illustrated, comprises a main supporting frame -1-having a circular platform 2- disposed in a substantially horizontalplane and supported by a series of, in this instance three, upright legs'-3 in uniformly spaced relation circumferentially, said legs beingextended above andbelow the plane of the platform -2- and are secured tosaid platform by bolts -4.

A circular band or ring 5 is secured by bolts 6- to the legs 3 to assistin holding the legs in fixed relation to each other and to saidplatform, said legs being preferably made of channel irons for impartingadditional rigidity and strength thereto.

The upper ends of the legs 3- are recessed at -7- to form shoulders -8which are engaged by the ring or band --5 to further stiffen the frameand legs.

A circular vat 20 is supported upon the platform -2 within the legs .-3-and ring or band -5- so that it may be readily removed by upwarddisplacement and is provided with a lid or cover 21- loosely restingupon its upper ed e.

A. tubular post -2% is secured at its lower end in registering openings--28- to the center of the platform -2 and the bottom of the vat---20-and rises above the bottom for receiving and guiding a verticallymovable plunger --29.

A perforated sheet metal plate 40 of substantially the same diameter asthat of the interior of the vat is supported in said vat a shortdistance above the bottom thereof by means of suitable feet orprojections -41- and is provided with perforations 42.

The object of this perforated plate is to allow the water to passtherethrough from the bottom upward and also from the top downward,which permits the clothes to be more thoroughly washed by the verticalreciprocatory dashers by reason of the fact that the water is free topass entirely through the clothes in reverse directions.

The plunger 2)- is tubular and extends entirely through and beyond theends of the post 27.

A yoke 43 is adjustably mounted upon the upper end of the plunger 29 andis held in its adjusted position by a removable locking bolt 4A which isadapted to enter one of a series of openings 45-- in the plunger forsupporting the dashers at different heights.

This yoke is provided with opposite downwardly curved arms 48 which areof substantially equal length and are provided at their outer ends withtubular heads 49 open at the bottom for receiving and supporting a pairof dashers -51.

Plunger reciprocatiwg mechanism.

A collar -61- is loosely mounted upon the lower end of the plunger 29and is held against endwise movement relative to said plunger by meansof a washer 62- and a ratchet wheel 63, both of which are secured tothe. plunger.

This collar is provided with apertured lugs -66 for receiving a pivotalpin -67 which projects beyond the outer faces of the lugs for supportinga pair of links -68, the latter being held in place by cotter pins'-69and are connected at their lower ends to one end of a vertically movablerocking lever 73 having its opposite end pivoted at 74-- to a bracket-75 on the under side of theplatform, said lever being connected by apitman --76 to a crank arm -77- on one end of a rotary shaft section 78.

This shaft section 78- is loosely journaled in one end of a tubularcountershaft -79- which is journaled in bearings -80 and 81 formingparts of separate gear cases -82- and 83-- both of which are secured tothe platform -2- as shown in Fig. 5, said shaft section 78 beingprovided with an annular groove 84-- for receiving a pair ofdiametrically opposite retainers 85 which are secured by screws 86- tothe adjacent sides of the sleeve or countershaft ,79 to hold the shaftsection -'78 against endwise movement relatively to said countershaft.

The inner end of the shaft section -78 is provided with a clutch face 87cooperating with a companion clutch face 88- on the adjacent end of aclutch section 89 within the sleeve 79-, the intermediate portion ofsaid clutch section 89 being provided with a diametrical slot -90therethrough for receiving a key or pin -9l which is secured to theopposite walls of the sleeve -79- to transmit rotary motion from saidsleeve to the clutch section 89 and to allow the clutch section to bemoved axially within the sleeve for engaging and disengaging its clutchface 88 with and from the companion clutch face 87-.

A spindle 92 coaxial with the sleeve 79- is loosely journaled at one end'in a bushing 93 in the outer end of the clutch section 88- and extendsoutwardly through a gear 94- on the outer end of the sleeve 79, theinner end of the spindle being provided with a head 95 interposedbetween the inner end of the bushing and end wall of a socket --96- inwhich the head is rotatable to hold the clutch section and spindleagainst relative endwise movement and at the same time permittingrelative rotation of the clutch section and spindle.

The outer end of the spindle 92 is provided with a grooved collar -97for engagement by a shifting arm 98- which is secured to a rock shaft 99in the gear case 83, one end of said rock shaft being extended through asuitable opening in the gear case and is secured to a. hand lever -100by which the shifting member 98' may be rocked in reverse directions forthrowing the clutch section 89- into and out of engagement with theshaft section 78 to start and stop the reciprocation of the plunger 29-and dashers 51 carried thereby. The means for transmitting motion to thecounter-shaft or sleeve 79 comprises an electric motor A having itsframe secured to the platform -2 and its motor shaft as a disposedhorizontally at right angles to the axis of the countershaft -79- asshown more clearly in Fig, 3, said motor shaft being preferably made insections coupled together by a universal joint -a' to compensate for anyslight variations in the alignment of the shaft sections.

A worm -B- is secured to a motor shaft section b which is journaled inbearings --Z)- in the gear case 82-- and is connected by a universalcoupling to a loose disc or collar --con the adjacent end of a coaxialmotor shaft section c'.

The disc c which is loose on the shaft section c is connected by afriction clutch -D to the shaft secti m c'--- to prevent stalling of themotor, said clutch comprising a disc -d secured by a pin d' in spacedrelation to the disc 0 to receive between them a fibre disc d Additionaldiscs e are loosely mounted upon the shaft section -0'- between the discd-- and adjacent end ofa coil spring -E which surrounds the shaftsection c'- and has its outer end abutting against an adjusting screw ornut e which is loose on the shaft section --c'- and is screwed into theadjacent end of an enclosing sleeve -F-- to adjust the tension of thespring and thereby regulate the friction between the several discs, theinner end of the sleeve F being rigidly .secured to the disc c.

The worm -B- meshes with a worm gear -f which is secured by a set screwf' to the periphery of the counter-shaft -79 as shown in Fig. 5, andserves to hold the counter-shaft --79 against endwise movement.

When the motor is in operation and the clutch section -89- is engagedwith the clutch face 87-, reciprocatory motion will be transmitted tothe plunger 29 through the medium of the pitman -76-, lever 73, link 68-and collar -61 for operating the dashers 5l.

Intermittent rotary motion.

The ratchet wheel -63-- is secured to the lower end of the plungerdirectly above the collar -6l which. has its upper end reduced indiameter to form a journal bearing for a horizontal rocking member -G-carrying a pawl g and a radial pin -g, the pawl g being spring pressedradially into engagement with the teeth of the ratchet wheel 63 torotate the plunger one or more tooth spaces at a time when the lever --Gis rocked in one direction and to permit said pawl to return freelyacross the face of the teeth.

A plate H is secured to the underside of the bed plate or platform 2 andextends downwardly therefrom, said plate being provided with a diagonalslot having its opposite walls forming cams h and --h, the lower end ofthe slot being open and disposed in the path of the vertically movablepin g' to receive said pin as the plunger approaches the limit of itsupward movement and to permit it to ride against the cam face -h forrocking the member C and pawl carried thereby and rotating the plungerwith the dashers thereon through a limited are as the pin continues itsupward movement along the cam face h, the opposite cam face -hserving toreturn the rocking member -G- to its starting position as the plunger ismoved downwardly.

The lower end of the slot in the plate H- is flared circnmferentially toassure the entrance of the pin into said slot when the plunger iselevated.

Wringe'r' driving mechanism.

The washing machine is equipped with a suitable wringer -I adapted to bemoved to and from a position across the upper end of the vat 20 andcomprises a frame -'i and a pair of rollers i which are adapted to berotated in reverse direction for feeding the clothes into and out of thevat.

The wringer frame z" is provided at one end with a gear case J having ahub mounted upon the upper end of a stationary supporting post j, asshown in Figs. 6 and 7 the lower end of said post being removablymounted on a tubular hub 83' of the gear case 83,

The wringer frame is preferably made in sections, one section carryingthe rollers z"- while the other section is removably mounted upon theupper end of the post j, the sections of the wringer being securedtogether end to end by bolts c' The upper portion of the post -jjustbelow the hub -jmay be attached to the circular band -5 or adjacent leg3- by means of a bracket -K-, which together with the bearing at thelower end of the post serves to hold it rigidly in an upright position,it being held against rotation by any suitable means, as, for example, aclamping plate -Is on the bracket K.

The portion of the post -j within the hub -j is provided with a seriesof, in this instance four, radial apertures -k arranged equal distancesapart circumferentially for receiving a locking bolt L- which isslidable radially in a socket and in one side of the hub j and is springpressed inwardly into the aperture kwhich may register therewith to holdthe wringer in its adjusted position, the outer end of the pawl or boltL being provided with a handle or knob M-- by which it may be withdrawnoutwardly against the action of its retracting spring to release thewringer frame and to allow it to be turned horizontally about the axisof the post y" to and from a position above one side of the tub or vat20.

The supporting shaft for the lower wringer roll z" is extended axiallyand journaled in a suitable bearing m in the wringer frame or in oneside of the gear case -J and is provided with a gear m'- secured theretoWithin said gear case. I

A vertical shaft N extends centrally through and beyond the oppositeends of the upright post j and has its lower end journaled in a bearing83' in the gear case 83- and its upper end in the gear case J, the lowerend of said shaft being provided with a gear -O meshing with the gear 94on the countershaft 79.

A pair of beveled gears o are loosely mounted upon the upper end. of theshaft -N within the gear case J and are normally engaged with the lowerand upper faces of the gear m.

ham-w lChe inner ends of the beveled gears o are provided with clutchfaces 0 adapted to be engaged by corresponding clutch faces on the endsof an interposed clutch collar -P which is splined upon the shaft ---l lto rotate therewith and to move end wise into and out of engagement theclutch faces 0.

A rock shaft -Q is ournaled in a suitable bearing --R- on the outer endof the gear case J- and is held against endwise ntiovement by anadjusting screw rwhich is engaged in a radial threaded aperture in thebearing B and enters an at. nular groove -1"-. The rock shaft Q isprovided with an eccentric pin -S carrying the roller -s which rides inthe annular groove in the collar to adjust said collar axially into andout of engagement with one or the other of the gears 0 according to thedirection in which it is ded to rotate the wringer-rolls, said rock tbeing provided with a hand piece by which it may be operated,
